MILTON J. WILLIAMS, OF CHICAGO, ILLINOIS.
PULVERIZER.
Specification of Letters Patent.
Patented Nov. 9, 1909.
Appltcatlon tiled February 16, 1908. Serial No. 478,218.
To all whom it may concern:
Be it known that I, Mluron J. 'iuaans, a citizen of the United States, residing at Chicago, Illinois, have invented a certain new and useful Improvement in Pulverizers, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which itzippertains to make and use the same, reference being bad to the accompanying drawin s, forming part also throuqh a of this specification, in whi Figure 1 is a vertical sectional view through a pulverizer constructed accordin to my improvement. Fig. 2 is a horizonta fragmentary sectional view through the same. Fi 3 is a detailed view of one of the guidc bars through which the hannuer su orts pass.
is invention relates to a new and useful improvement in pulverizers of that type commercially known as the \V mills. characterized by the pivoted revolving hammers which act upon the material as it enters the machine at. the hopper or feed end thereof, crushing said material as it rests u on the bottom of the ho per, or breaker p ate, as it is sometimes ca led, the material being further disintegrated or crushed by the hammers the material is carried over the cage or grinding surface. The crushed material falls through the openings in the cage or grindin surface into a suitable receptacle located )cncath the machine. The hammers or heaters which revolve about the shaft,
iiliams acting thereon as while made of a material whose resistance to wear is its essential quality, will, in time, wear away at their striking ends, and the farther these striking ends are removed from the breaker plate and grindiu" surface. the less becomes the capacity of l to machine.
It is the purpose of my present invention to provide means whereby thcsc revolving hammers or boaters may be adjusted outwardly to take up this wear (or inwardly, il' occasion requires, as when a new cage is introduced to replace a worn one). said means consisting of inclined rods which are movable longitudinally the shaft for ell'crting simulhunmns and uniform adjustment of all of the hnnnners or heaters inwardly and outwardly.
In the drawings. l indicates the breaker plate, 3 the grinding surface or cage. and l the cover of t to lnaehimi, which may or may not. be hung, as desired.
the casing, :2
5 is a shaft mounted in hearings in the side frame of the machine driven in any suitable manner.
6 are disks in the form fixed to shaft 7 are the head pieces of a frame, said frame consisting of said head pieces and in clined rods 8 connecting them. To one of these hcad ieces are secured threaded rods 9 passing tn-ou h one of the disks 6 and late 10 secured to the disks 6, on cam si e of which plate It) are arranged nuts 11 on said rods 9.
12 indicates burs whose ends are supported by the disks 6, said bars being provided with radially disposed openings in which are slidingly mounted hammer supports 13. In the outer ends of these hammer supports are pivot bolts 14 on which the hammers 15 are pivoted. The inner ends of the hammer su ports 13 are )rovided with openings throng which the inclined rods 8 pass.
In operation, when the striking ends of the hammers wear, the nuts on the rods 9 are adjusted so as to move the head )ieces 7 and the inclined rods 8 longitudinal Y the shaft in a direction tending to force the hammer supports 13 outwardly. In this way the wear of the hammers is taken up.
\Vhcn it is desired to put. in a new cage. the frame coutainin the inclined rods is moved in an rnposite direction so as to positively withdraw the hammer supports inwardly toward the shaft.
I am aware that minor changes in the construction. arrangement and combination of the several parts of my device can be made and substituted for those herein shown and described without in the least. departing from the nature and principle of my inventiou.
In using the expression disks in the foregoing specification and in the following claims. I wish to he understood as not confining; myself to circular disks. as the parts which perform the functions of the sup )(llling disks described and claimed could in in the shape of spider-arms. or other forms, metal being. cut away at various places, where. it. was not needed, to lighten the ma chine.
Having: thus described my invention. what claim is:
I. in a pnl\'e|'izer.'tlncombination with a casing, of a shaft, slotted humnwr snpporb ing burs carried by the shaft. bnnmnn' supof head castings r rts arranged to slide through the slotted rs, hammers mounted between the outer ends of said supports, and means coiiperating with the inner ends of said supports to move them and their carried hammers outsupports for positively adjusting said hamlner supports inwardly and outwardly.
3. In a pulverizer, the combination with a shaft disks carried thereby, guide bars carried by said disks, hammer supports arranged to slide through said bars, hammers pivotally carried by said supports and a frame movable lo itudinally the shaft, said frame having inc med rods engaging said hammer supports.
4. In a pulverizer, the combination with a casing, a shaft mounted in said casing, hammer sup orts movable radially with respect to said aft, hammers pivotally carried by said supports inclined rods passin through openings in the inner ends of sai hammer supports, means for moving said rods longitudmally relative to said shaft, and means whereby the rod-moving means is locked after movement.
5. In a pulverizer, a casing, a shaft journaled therein, a series of slotted bars carried by the shaft, hammer supports carried by the slotted bars and arranged to move rad|- ally relative to the shaft, revolving hammers pivotally carried by the outer ends of the hammer supports, there being openings formed in the inner ends of the hammer su ports, inclined rods passing through said openings, disks arranged to slide u n the shaft and engaging the ends of the inclined rods, and adjustable means engaging one of the disks for shifting the same and the inclined rods.
In testimony whereof I hereunto affix my signature in the presence of two witnesses, this 8th day of February, 1909.
